To all (wlwm'z't may concern:

Be it known that I, LUTHER CQLAsHnE'r,

' a. citizen \of'the United States, residing at Jacksonville, in the county of Morgan and State of Illinois, "have invented CBITtLlIl; new

and useful Improvementsin Water-Purifying, Devices,.of which. the followmg is 1a .Myrinvention relates to water purifying devices, particularly :to that typeemploying electricity.v asfthe purifying agent, and-has for its broad. object theprovision of an apparatus whereby Water containing mineral salts in. solution and. contaminated by the 1 presence of organic matter, such as bacteria and germs, may be purified by the'action of electricity and rendered fit for use.

The principle involved in1,the carrying out ofmy invention is that the action of :an

electric current passing through water containing mineral and organic matter decomposes -or breaks up the water into its component gases, hydrogen and oxygen. Experiment has revealed the :fact that the oxyg5, gen gas has a peculiar chemical action on the mineral and organic matter destroying the life'of the organic matter and converting the :mineral salts held inqsolution into other compounds insoluble in Water, the

hydrogen gas passing off into the air.

The apparatus employed in carryingxout my invention consists of an electrolyzing device wherein the previously described principle may be applied, aerating means whereby. the gases. may-be permitted to escape,

and a settling tank whereln therefuse-Inattermay be removed from suspension sedimentation. I

The specific object of my invention is the to provision of a novel device wherein a con tinuous flow of impure water may be subjected to electrolysis while the influx of the Water itselfoperates positive means for accomplishing the proper and continuous agii5. tation of the water so thatall of it may be thoroughly acted upon. h

Other objects and advantages residing in the particular details oflconstruction andarrangement ofparts will be carefully brought 5.0 out in the following description and illustrated in the accompanying drawings, in which: p

- Figure 1 is a viewtin elevation of my entire apparatus, F ig. 2 is a longitudinal sectional view through the electrolyzing device, Figs. 3, 4 and 5 are cross sectional views on the lines 3 ,3, ll .and 55 of Fig. 2, and Eig. 6 is a detail sectional view of one of the bearings. I v

Referring more particularly to the drawings, thenumerall designates the electrolyzing device as a Whole, which comprises a preferably rectangular open-topped tank 2 formedv of insulating material preferably.

Disposed through one endof the tank-2.

is a member 3 having at its outer end a head 4 bearing against a washer 5, and having at its inner end a socket. The member 8 is held in place by a nut 6 threaded upon its inner end and bearing against a washer 7. A bushing 8 is disposed through the other end of the tank and is threaded upon its inner end for the reception of a nut '9 bearingv against a Washer l0.- The head or outer end of the bushing 8'bears against a Washer 11 which is also engaged by a cup 152 thread-- ed upon the head of the bushing 8 for a purpose to be described, the cup 12 being provided with a hole closed by a plug 13.

I head 15 and provided upon its inner end with a reduced screw-threaded. extension 16. A shaft 17 is disposed longitudinally Within the tank 2 and has at one end an extension 18 engaging within the socket in the member 3, and has at its other end a threaded socket engagingitheextension 16 on the spindle 14. Theshaft 17 is thus freely revoluble' in relation'to the tank.

Disposed upon the shaft 17 at regular intervals are electrodes 19 formed as circular metallic disks incapable of rotation on. the shaft. These disks are held in their proper spaced relation-by metallic sleeves QO-disposedupon'the shaft, the sleeves 20 being covered by other sleeves 21 formed of insulating. material. The ends of the shaft 17 are screw-threaded for the reception of nuts 22 engaging the endlnost sleeves and locking the disks and sleeves securely together upon the shaft. The shaft 17 and the electrodes 19 constitute the movableportion of my electrolyzer.

' In order that the shaft 17 carrying the I electrodes 19 maybe rotated, I provide a bucketed wheel 23 on the :shaft 17 and clamped in place by a nut 2 l 7 VVater to be purified 1S admitted to the tank 2 through an inlet pipe 25 which is held in vertically adjustable relation to the tank by being threaded through abracket 26 secured on the tank. Thehorizontal portion'27 of the'inlet'pipe passes through a vertically slotted guide, 28 and communicates with a discharge nozzle 29 disposed to play upon the wheel 23, adjustment of the streambeing effected by any suitable valve.

structure indicated at 30. A water' outlet pipe 31 is provided at. the upper portion of the other end of the tank.

' The stationary electrodes comprise a: pm? .ralityof metallic plates 32and 33 arranged 'inalternation between thedisksg-19. and

connected by metal rods 34 having nuts 35 upon their ends. These plate-s are held in their proper spaced relation by-metallic i as shown for-the passage ofthe shaft 17 I sleeves 346 disposed upon the rods 34:. and abutting against the successive plates, the

sleeves 3e being'covered by other sleeves 3t of insulating material. The plates 32 rest upon the bottom of the tank 2 wh le the plates. 33 are spaced above the bottom and extend above the plates .32,1-the-purpose being to cause thewater in the tank to pursue a course. indicated by the arrows, whereby perfect and complete circulation is ma1n-' tained. The plates 32and 33 are .apertured and the sleeves carried upon it.

The electric. circuit comprises a suitable source of current 36 having one terminal connected with one of the rods 3l-and its passage of the current decomposes "the waother terminal connected with the cup 12.

Mercury .37 is placed within 7 this cup through'the opening closed by the plug shown and contacts'with the head 15 of the spindle 7 14, consequently making complete connectionfthrough the shaft 17 and the" disks 19;. The current willofcourse pass through thewater in the tank between the plates 19 and 32, and 1 9fand 33. vThe ter into hydrogen andoxygenp The'hydror' the waterrises in the tank the insoluble impurities will be carried with-.itout through the pipe 31.
